The IEC 60099-5 standard, officially titled "Surge arresters – Part 5: Selection and application recommendations," provides critical guidance for choosing and using surge arresters in three-phase systems with nominal voltages above 1 kV. Core Purpose & Scope

The 2018 edition (Edition 3.0) introduced significant technical revisions to align with the new classification system used in the testing standard IEC 60099-4:2014. iTeh Standards IEC 60099-5:2018 iec 600995 pdf

Line Discharge Classes

For high-voltage transmission systems, arresters are classified by "Line Discharge Classes" (Class 1 through 5). The IEC 60099-5 standard, officially titled "Surge arresters

New sections (Annexes H and I) were added to help users transition from old classifications to the new charge-based metrics. Expanded Calculations: New sections (Annexes H and I) were added

2. The Most Likely Intent: IEC 60095 (Lead-Acid Starter Batteries)

If you need a standard for lead-acid batteries used for starting internal combustion engines (cars, trucks, motorcycles), the correct series is IEC 60095.

(often searched as "IEC 60099-5 PDF") is the essential international guideline for the selection and application of surge arresters in power systems. It provides, in a non-mandatory format, the necessary information and technical recommendations to protect electrical infrastructure—such as transformers, substations, and overhead transmission lines—from lightning and switching overvoltages. This article summarizes the key aspects of the 2018 edition (Edition 3.0)

According to IEC 60099-5, the following factors should be considered when selecting a surge arrester:
